Endoscope control methods

ABSTRACT

Described herein are methods for reversibly constraining an endoscope. A method may include positioning an elongate medical device or endoscope in a holder of a clamp. A method may include actuating the holder such that one or more of a first sidewall and a second sidewall of the holder move to a clamped configuration to exert a force on the endoscope. A method may include adjusting a pad of the clamp from a first position to a second position where the pad is in contact with the endoscope in the second position.

TECHNICAL FIELD

This disclosure relates generally to the field of intraluminal devices, and more specifically to the field of endoscopy. Described herein are endoscope control devices.

BACKGROUND

Endoscopy uses thin flexible tubes that are inserted into the body's openings (e.g., mouth, anus, etc.) or through incisions to study tissues, perform biopsies, and/or deliver therapy or treatments. Frequently, organ systems such as the gastrointestinal tract, respiratory tract, urinary tract, and female reproductive tract are studied and/or treated using endoscopes. Endoscopes are also common in various types of laparoscopic procedures, where the endoscope is inserted minimally invasively into an incision near the tissue of interest. Depending on the tissue to be studied and/or the treatment to be performed, endoscopes may be equipped, either on a distal end or via passage through a lumen of the endoscope, with a diverse array of functionality: electrocauterization tools, cameras, lights, irrigation, air, ultrasound probes, resection tools (e.g., needles), etc. FIG. 1 shows an example of a typical endoscope 100. As can be seen in FIG. 1 , the functionality of a typical endoscope is vast and further includes articulation knobs for articulating a distal end of the endoscope.

During endoscopy procedures, physicians must perform several tasks nearly simultaneously or in rapid succession. For example, during an endoscopy procedure, the scope needs to be stabilized, manipulated, and/or controlled translationally and rotationally without damaging the endoscope or inflicting harm on the patient. In addition, the physician needs to modulate and control air/water flow from valve 140; suction from valve 110; imaging modalities, like camera 120; treatment modalities from channel 130; etc. and articulate the distal end 150 of the endoscope 100, typically using knobs 160 for left and right articulation, as shown in FIG. 1 . This immense number of tasks performed by the physician can result in physician fatigue and discomfort and ultimately damage to tendons and muscles in the physician's upper body. Further, at least one additional assistant is required to fully perform an endoscope procedure—either to hold the endoscope while various functionality of the endoscope is deployed or to operate the endoscope or a computing system in electrical communication with the endoscope, resulting in increased overhead for the hospital.

Accordingly, a device is needed for use during endoscopy procedures that performs at least a few of the tasks outlined above. Various laparoscopic assistance tools exist but are poorly equipped for the unique requirements of endoscopy. Further, devices exist that tether or adhere to the patient during the endoscope procedure. However, these devices can be uncomfortable for the patient due to the translational and rotational requirements of an endoscope during an endoscopy procedure. Robotic systems also exist for certain surgical applications but may be too cumbersome for certain endoscopy procedures. Taken together, there exists a need for new devices for endoscope control.

DETAILED DESCRIPTION

The foregoing is a summary, and thus, necessarily limited in detail. The above-mentioned aspects, as well as other aspects, features, and advantages of the present technology will now be described in connection with various embodiments. The inclusion of the following embodiments is not intended to limit the disclosure to these embodiments, but rather to enable any person skilled in the art to make and use the contemplated invention(s). Other embodiments may be utilized and modifications may be made without departing from the spirit or scope of the subject matter presented herein. Aspects of the disclosure, as described and illustrated herein, can be arranged, combined, modified, and designed in a variety of different formulations, all of which are explicitly contemplated and form part of this disclosure.

The devices described herein are configured for use with any elongate device: endoscopes, catheters, probes, etc. Exemplary non-limiting embodiments of elongate devices or endoscopes include: gastroscope, duodenoscope, colonoscope, sigmoidoscope, enteroscope, bronchoscope, ureteroscope, cystoscope, rhino-laryngoscope, laparo-thoracoscope, mobile airway scope, choledochoscope, etc.

The devices described herein may be configured for a wide variety of endoscope sizes; for example, elongate devices having an outer diameter of 9 to 11.4 mm, 10.8 to 12.5 mm, 12.9 to 13.7 mm, 21.8 to 13.2 mm, 10.5 to 11.7 mm, 5.7 to 6 mm, 2.8 to 13.2 mm, 10.5 to 11.7 mm, 5.7 to 6 mm, 2.8 to 3.3 mm, 5.4 to 5.5 mm, 2.6 to 4.9 mm, 7 mm, 4.1 to 5.2 mm, 2.8 to 5.2 mm, 5.9 to 6 mm, 11.5 to 11.6 mm, 4.4 to 5.1 mm, or any range or subrange therebetween.

Disclosed herein are endoscope control devices 210. As shown in FIGS. 2A-2B, such devices, in general, include a base positionable proximate (e.g., on a bed, floor, table, stand, etc.) a patient 230, a column extending vertically from the base, an arm extending horizontally from the column, and a clamp movable or fixedly coupled to the arm. Such devices function to position an endoscope proximate to or in contact with a patient 230. A base of endoscope control device 210 may be positioned under a mattress 220 on a surgical or hospital bed or platform, such that a weight of the patient and/or mattress further stabilizes the endoscope control device 210. In other embodiments, endoscope control device 210 is positionable on the floor and comprises two or more legs (e.g., tripod, ladder configuration, etc.) or one or more wheels. For example, the endoscope control device 210 may be movable between locations on the one or more wheels. An endoscope control device 210 may be configured to be disassembled and stored and/or transported to a second location. For example, one or more legs of the base may be removable, the column may be separable from the arm and/or the base, and/or the clamp may be separable from the arm. One or more components of the endoscope control devices 210 described herein may be disposable. One or more components of the endoscope control devices 210 described herein are configured for use with a surgical drape 240, as shown in FIG. 2B, to maintain the one or more components out of the surgical field and free from contamination. The surgical drape 240 may be configured to substantially cover a clamp, arm, column, and/or base of an endoscope control device 210.

Further, the endoscope control devices 210 described herein are configured to grip an endoscope with a first, lesser force such that the endoscope remains axially and rotationally translatable; an intermediate force such that the endoscope is either axially or rotationally translatable; or with a maximum force such that the endoscope is neither axially nor rotationally translatable. Of course, there are degrees of force that restrict axial and rotational translation therebetween such that there may be an infinite number of degrees of force that impact axial and/or rotational movement of an endoscope device positioned therein. The intermediate configurations are also further configured to modulate the clamping force of a clamp from unclamped (i.e., no force applied to endoscope) to fully clamped (i.e., endoscope is completely rotationally and translationally restrained).

As shown in FIGS. 3-4 and 7-8 , a device for reversibly constraining an endoscope includes a base 360, 460, 760, 860 positionable proximate a patient. The base 360, 460, 760, 860 functions to structurally support a column 370, 470, 770, 870 and an arm 380, 480 of the endoscope control device 310, 410. The base 360, 460, 760, 860 further functions to rest or be positioned on a surface, for example a floor, bed, counter, or other surface that is proximate a patient. For example, the base may be positioned such that a clamp 350, 450 of an endoscope control device 310, 410 is within 1 to 10 mm, 0.5 to 5 cm, 1 to 10 cm, or any range or subrange therebetween of a bodily opening or incision of a patient. In one non-limiting embodiment, as shown in FIGS. 7-8 , base 760 (860) includes legs 762 a, 762 b (862 a, 862 b) and body 764 (864). Legs 762 a, 762 b (862 a, 862 b) are insertable under a mattress, for example, and/or rest on a surface to support the endoscope control device 310, 410. The legs 762 a, 762 b (862 a, 862 b) may comprise a light-weight material, for example aluminum, titanium, or magnesium. The legs 762 a, 762 b (862 a, 862 b) may be substantially flat, cylindrical, or otherwise. As shown in FIG. 8 , legs 862 a, 862 b are reversibly insertable into leg receiving areas 852 a, 852 b defined by body 864. Legs 862 a, 862 b are secured via one or more fasteners (e.g., grub screws) to body 864 once positioned in leg receiving area 852 a, 852 b. Alternatively, legs 862 a, 862 b and body 864 form a monolithic support structure such that legs 862 a, 862 b and body 864 are irreversibly connected or machined or manufactured as one component.

As shown in FIG. 4 , endoscope control device 410 further includes a column 470 extending vertically from base 460, more specifically from body 864 as shown in FIG. 8 . As shown in FIG. 4 , column 470 extends vertically in a y direction from a base 460 in an xz plane. Column 470 is further pivotally coupled to the base 460, more specifically body 464, such that column 470, 870 rotates around a y-axis 872, as shown in FIG. 8 . Body 864 defines aperture 838 that is sized and shaped to receive connector portion 836 of column 870 through plate 842. Sleeve bearing 848 is received in aperture 838 to prevent connector portion 836 from rubbing on body 864 during rotation. Plate 842 defines aperture 832 that is configured to receive a protruding portion of rotating flange 844. Screw 854 on rotating flange 844 is configured to secure column 870 (e.g., translationally and/or rotationally) in rotating flange 844. Connector portion 836 further comprises seat 856 configured to contact screw 854 and provide torsional force on column 870. Rotating flange 844 includes a plurality of detents therein such that pin 846, when manipulated (e.g., lifted, raised, moved, etc.) allows rotating flange 844 to rotate thereby causing rotation 872 in column 870. Release of pin 846 allows pin 846 to insert in one of the plurality of detents in rotating flange 844 which prevents further rotation of rotating flange 844 thereby preventing rotation of column 870. In some embodiments, the detents are positioned in 5°, 10°, 15°, or 20° increments relative to on another. In other embodiments, the detents may be positioned in 0 to 25° increments, 25 to 50° increments, 50 to 75° increments, 75 to 100° increments, 100 to 125° increments, 125 to 150° increments, 150 to 175° increments, 175 to 200° increments, 200 to 225° increments, 225 to 250° increments, 250 to 275° increments, 270 to 300° increments, 300 to 325° increments, 325 to 350° increments, or any range or subrange therebetween. Column 870 pivots or rotates (arrow 872) relative to the body 864 so that base 860 is positionable perpendicular to the patient or surface on which the base 860 rests and the column 870 is pivotable relative to the patient to position a clamp in proximity to a bodily opening or incision of a patient.

Returning to FIG. 4 , an endoscope control device 410 further includes an arm 480 extending horizontally, in an xz-plane, from the column 470. The arm 480 functions to enable positioning of a clamp 450 in proximity to a bodily opening or incision of a patient. Arm 480 is configured to translate vertically (arrow 484), along a y-axis, along the column 470 via adjustable block 900, as shown in FIG. 9 . Adjustable block 900 defines arm receiving aperture 912 into which an arm, such as arm 480, is insertable and, in some embodiments, translatable therein. For example, arm 480 further comprises one or more detents 478 along its length so that arm 480 translates horizontally through adjustable block 900 (arrow 482), along an x-axis, relative to the column 470 and locks into position at any one of the detent locations within the adjustable block 900, as shown in FIGS. 4 and 9 .

Further, as shown in FIGS. 4 and 9 , movement 484 of arm 480 in a y-direction relative to column 470 is also through adjustable block 900. Adjustable block 900 further comprises a spring 914 loaded cam action plate 916. The plate 916 is spring 914 biased to maintain position of the adjustable block 900 when a downward force 918 is applied on adjustable block 900, arm 480, and/or clamp 450. In some embodiments, column 450 includes one or more serrations configured to maintain position of the adjustable block 900 when an upward force 922 is applied to adjustable block 900, arm 480, and/or clamp 450. In other embodiments, adjustable block 900 further includes a second cam action plate that is spring-biased and configured to maintain position of the adjustable block 900 when an upward force 922 is applied on adjustable block 900, arm 480, and/or clamp 450.

Turning to FIGS. 5A-6 , an endoscope control device further includes a clamp 550, 650. As shown in FIG. 5A, clamp 550 functions to receive endoscope 572 therein and apply a force circumferentially to the endoscope 572 to reduce or prevent axial and/or rotational translation of the endoscope 572 and to avoid discrete loading on the sides of the endoscope 572. Various clamp configurations are shown in FIGS. 5A-6 and 10-12 . Focusing on an exploded view of clamp 650 shown in FIG. 6 , clamp 650 is actuatable via lever 652 and lead screw 654 on a first side or holder side of the clamp and knob 676 and lead screw 674 on a second side or pad side of the clamp. Plate 690 defining aperture 697 interfaces with threads of lead screw 654, allowing wall 692 to be pushed and pulled with the lead screw 654. A holder 664 includes a first or top sidewall 656 a and a second or bottom sidewall 656 b, which together define an endoscope receiving area 662. Endoscope receiving area 662 defines a substantially hemi-cylindrical shaped surface for contacting and forcibly restraining an endoscope received therein. The first or top sidewall 556 a, 656 a and the second or bottom sidewall 556 b, 656 b are movable or transitionable between a first or open configuration (FIG. 5A) in which the first or top sidewall 556 a, 656 a and the second or bottom sidewall 556 b, 656 b are configured to set apart from an endoscope 572 when positioned in the endoscope receiving area 562, 662, as shown in FIGS. 5A-6 , and a second or closed or clamped configuration (FIG. 5B) in which the first sidewall 556 a, 656 a and the second sidewall 556 b, 656 b are configured to clamp the endoscope 572 when positioned in the endoscope receiving area 562, 662, as shown in FIG. 5B. In some embodiments, holder 664 comprises an asymmetric holder such that the second sidewall 656 b is longer than the first sidewall 656 a. For example, a second sidewall 656 b may be 10% to 15%, 15% to 20%, 20% to 25%, 25% to 30%, 30% to 35%, 35% to 40%, 40% to 45%, 45% to 50%, 50% to 55%, 55% to 60%, 60% to 65%, 65% to 70%, 70% to 75%, 75% to 80%, 80% to 85%, 85% to 90%, 90% to 95%, or 95% to 100% longer than a first sidewall 656 a. In such asymmetric holder embodiments, the endoscope is configured to rest on the second sidewall 656 b when the asymmetric holder is in the first or open or unclamped configuration. Alternatively or additionally, holder 664 further includes a third sidewall 656 c that further forms or defines a hemicylindrical surface of endoscope receiving area 662.

Lever 652 is configured to move the first sidewall 656 a and second sidewall 656 b between the first and second configurations. For example, lever 652 may be movable between two configurations, for example a released or unclamped configuration as in FIG. 5A and an actuated or clamped configuration as in FIG. 5B, or a plurality of positions to effectuate movement of the first sidewall 656 a and the second sidewall 656 b. Further for example, in some embodiments, lever 652 effectuates movement of the first and second sidewalls 656 a, 656 b between one or more intermediate configurations between the first and second configurations. As lever 652 is used to rotate lever body 694, lead screw 654 is advanced, pushing wall 692 and holder 664 with endoscope 572 positioned therein against pad 658 and one or more supporting elements of pad 658 (e.g., plate 678, lead screw 674 that is mounted in support wall 672). This movement of lead screw and ultimately holder 664 is configured to cause an inward movement of sidewalls 656 a, 656 b, resulting in an area of the endoscope receiving area 662 to be reduced such that the sidewalls 656 a, 656 b increase a circumferential contact with an endoscope positioned in the endoscope receiving area 662. This circumferential contact about the endoscope 572 grips the endoscope 572 similar to that imposed by a human hand and fingers. Continued motion of lever 652 increases the advancement of holder 664 towards pad 658, resulting in increasing circumferential contact and therefore grip force about the endoscope body.

In some embodiments, as lever 652 is actuated 90 degrees, lead screw 654 is advanced ¼ inch; in other embodiments, lever 652 is actuated n degrees (e.g., n equals any number from 1-360 degrees) which advances the lead screw 0 to 1 inch, for example 0 to 0.1 inches, 0.1 to 0.2 inches, 0.1 to 0.25 inches, 0.2 to 0.3 inches, 0.3 to 0.4 inches, 0.4 to 0.5 inches, 0.5 to 0.6 inches, 0.6 to 0.75 inches, 0.7 to 0.8 inches, 0.8 to 0.9 inches, 0.9 to 1 inch, etc. One or more detents or grooves in lever body 694 interact with a spring-loaded ball detent mechanism 698 (which is fixed in support 682) to enable lever 652 to lock into any one of the positions. In some embodiments, an operator of the lever 652 or clamp 650 may receive audible (e.g., ball detent mechanism click), haptic (e.g., piezoelectric mechanism in lever body that initiates vibration when locked into any one of the positions, a user feeling a click of the detent mechanism, etc.), and/or visual (e.g., light is activated when locked into any one of the positions) feedback to indicate when the lever 652 is locked into any one of the positions.

Further, as shown in FIGS. 5A-6 , an endoscope control device 550, 650 includes a pad 558, 658 opposite the endoscope receiving area 562, 662. Pad 558, 658 functions to contact an endoscope 572 positioned in clamp 550, 650 to prevent endoscope 572 from being displaced from endoscope receiving area 562, 662 as sidewalls 656 a, 656 b (optionally) 656 c are moved from a first configuration to a second configuration to clamp the endoscope therein. Additionally, pad 558, 658 functions as a static wall that functions as a stop for advancement of holder 664. As such, pad 558, 658 is movable between a first or open position, as shown in FIG. 5A and a second or closed position, as shown in FIG. 5B. In the second or closed position, pad 558, 658 applies a force to endoscope 572 positioned therein. Pad 558, 658 may further include one or more or a plurality of intermediate configurations such that pad 558, 658 is adjustable to allow for endoscope of varying diameters. As shown in FIG. 6 , knob 676 rotates lead screw 674 through support wall 672, which moves plate 678 coupled to pad 658 either forward to contact an endoscope positioned therein or retracts plate 678 coupled to pad 658 to disengage from an endoscope positioned therein. Plate 678 is prevented from rotating with lead screw 674 by dowel pins 696 which are fixed in plate 678, but slide freely in support wall 672, thereby supplying rotational resistance of plate 678.

Support 682 functions as a platform for coupling together various elements of clamp 650. Support 682 rotates relative to flange 684 on pivot 686 which is fixed to support 682. Base 688 is attached to flange 684 (via one or more fasteners, for example 4 screws), and is coupled to an arm of the endoscope control device. Washer 689, wave spring 685, and external ring clip 691 collectively function to secure flange 684 to pivot 686 and provide rotational friction. In some embodiments, base 488 translates horizontally (arrow 482) along arm 480, as shown in FIG. 4 , via a complementary detent mechanism in arm 480 and base 488. For example, spring-loaded ball detent 642 (shown in FIG. 6 ) interacts with the one or more detents 478 along arm 480 (shown in FIG. 4 ). In other embodiments, base 488 is fixedly connected to arm 480 at a distal end 486 (or any position along arm 480) of arm 480.

Turning now to FIGS. 10A-12B, which show alternative clamp embodiments. FIG. 10A shows clamp 1000 in the open, unloaded configuration, and FIG. 10B shows clamp 1000 in the closed, clamped configuration. Clamp 1000 shown in FIGS. 10A-10B comprises holder 1004 which defines entry aperture 1002 through which an endoscope is inserted into clamp 1000 and endoscope receiving area 1022 in which an endoscope is clamped by sidewall 1008 and pads 1010 a, 1010 b. FIG. 10B shows clamp 1000 in a closed or clamped configuration such that an endoscope positioned in endoscope receiving area 1022 is restrained axially and/or rotationally. In the closed configuration, eccentric lever 1006 (i.e., cam action lever) is configured to displace sidewall 1008 and pad 1010 a to restrain an endoscope positioned in endoscope receiving area 1022. Sidewall 1008 and pad 1010 a is preferably curved so that it contacts an endoscope positioned therein along a circumferential line of the endoscope. In an open or unclamped configuration, as shown in FIG. 10A, eccentric lever 1006 does not substantially displace sidewall 1008 and pad 1010 a such that sidewall 1008 and pad 1010 a is in proximity to a center of rotation 1018 of eccentric lever 1006 and an endoscope positioned within clamp 1000 is unrestrained.

Turning to FIGS. 11A-11B which show an alternative embodiment of a clamp 1100. As shown in FIG. 11B, in a closed or clamped configuration, eccentric lever 1106 activates sidewalls 1108 a, 1108 b which cause pads 1110 a, 1110 b to contact an endoscope positioned within holder 1104 on opposing sides of the endoscope to axially and/or rotationally restrain the endoscope. Holder 1104 defines endoscope receiving area 1122 for holding an endoscope during clamping. The endoscope is positioned in holder 1104 through entry aperture 1102 defined by holder 1104. In an open or unclamped configuration, as shown in FIG. 11A, eccentric lever 1106 does not substantially displace sidewalls 1108 a, 1108 b and therefore pads 1110 a, 1110 b such that an endoscope positioned within clamp 1100 is unrestrained. Further, side plates 1112 (one on each side of holder 1104) guide the endoscope into the endoscope receiving area 1122. Inner edges 1114 of side plates 1112 maintain the endoscope elevated above a surface of the pads 1110 a, 1110 b when the endoscope is unlocked to allow the endoscope to move freely in holder 1104.

Turning to FIGS. 12A-12B which show another embodiment of a clamp 1200. As shown in FIG. 12B, holder 1204 defines entry aperture 1202 through which an endoscope is inserted into clamp 1200 and into endoscope receiving area 1222 which holds an endoscope during clamping. In a clamped or closed configuration, as shown in FIG. 12B, rotating rotatable column 1214 (e.g., 90 degrees, 45-90 degrees, 75 to 100 degrees, etc.) will rotate pusher 1212, causing it to displace downward due to its upper curved cam surface interacting with the inner curved surface of the holder 1204. This will cause pad 1210 a to advance towards pad 1210 b in holder 1204, thereby clamping an endoscope in between pads 1210 a, 1210 b. In an open or unclamped configuration, as shown in FIG. 12A, rotatable column 1214 is retracted via a compression spring that maintains the upper surface of pusher 1212 against the inner surface of holder 1204, so that it does not contact or restrain an endoscope positioned in endoscope receiving area 1222.

Turning to FIG. 13 , which shows a method 1300 of using one or more endoscope control devices described elsewhere herein. As shown in FIG. 13 , a method of using one or more endoscope control devices includes positioning an endoscope in a holder of a clamp S1310; optionally (indicated by dashed lines around block S1320) adjusting a pad from a first position to a second position, wherein, in the second position, the endoscope is configured to contact a second surface of the endoscope that is opposite a first surface of the endoscope that is in contact with the holder S1320; and actuating the holder such that one or more of a first sidewall and/or a second sidewall of the holder move to a second or clamped configuration to exert a force to restrict axial and/or rotational movement of the endoscope S1330.
